Mobiledia has a post about Raytheon, a US defense contractor, developing some sort of an Android app for the armed forces.

It combines maps with buddy lists to help soldiers find enemies in the battlefield. The so called Android Tactical System, or RATS for short, can pick up aerial images from an unmanned aircrafts and satellites and then focus in on details such as license plates on cars or a person's facial features. For instance, a soldier could tag an unmanned plane as a "buddy," track its progress on a map using the phone and then access streaming video from the plane for a bird's eye view of the area. It could also help to track other squad members or even enemies.

According to Mobiledia, Rytheon selected Android "due to its open-source nature, which made developing applications easy." So far, US Special Forces have tested the product on Android-powered Motorola and HTC devices. Raytheon even got Google's help on this.

The devices still lack basic security measures such as encryption or identity recognition software.
